Looking for a simple circuit to control the light intensity of Light Emitting Diodes (LEDs) or similar lighting sources? Here is an Arduino based circuit with three independent pulse width modulated ...

Using a circuit simulator can get you part of the way and software simulators abound. But cosimulation — simulating both analog circuits and a running processor — is often only found in high ...

The 7-segments LED devices The general principle behind this kind of devices is the same that makes the common LEDs working. To get a LED lighting we should connect its ground pin to the circuit GND ...
